CLOSURE FOR VESSELS.

srncrmcnmron forming part of Letters Patent No. 626,015, dated May 30, 1899.

Application filed February 9, 1899. Serial No. 705,013. (No model.)

To all whom it may concern: 7 Be it known that I, ARTHUR FRANCIS BARD- WELL, a citizen of the United States, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented a new and useful Improvement in Closures for V'essels, of which the following is a specification, reference being had to the accompanying drawings, in which- Figure 1 is an elevation of a vessel fitted with my improved closure. Fig. 2 is a top plan view of my improved closure. Fig. 3 is a section on line 3 3 of Fig. 1 and on line 3 3 of Fig. 2. of Fig. 3. Fig. 5 is a side elevation of the cover-fastener jointed on the wire collar. Fig. 6 is a front elevation of what is shown in Fig. 5. Fig. 7 is a side elevation of the cover-fastener as used detached and without the wire collar. Fig. 8 is a-front elevation of what is shown in Fig. 7. showing the manner of securing the ends of the wire collar.

The object of my invention is to provide an efficient yet inexpensive closure for vessels, having special reference to those vessels which are designed to hold preserves and other substances out of contact with which it is necessary to keep the air.

One feature of my invention is the coverfastener, which presses the cover firmly and closely on its seat and which is cheap in man ufacture and readily applied and released in use. Another feature of my invention is the cover, the upper surface of which is formed with a groove adapted to engage a projecting catch on the cover-fastener, and the under surface of which is adapted to receive a rubber ring which hermetically seals the joint between the cover and the vessel. My invention consists in the cover-fastener herein described and in thecombinations hereinafter described and claimed.

In the drawings illustrating the principle of my invention and the best mode now known to me of applying that principle, A is the jar, the upper portion of the neck of which is enlarged, forming a flange B 13. Around the neck of the jar A and under the flange 13 passes a wire collar D, the ends d d of which are bent downwardly. The wire D is drawn snugly around the neck of the jar A by pass- Fig. 4 is a section on line 4 4:-

Fig. 9 is a detail ing over the ends d d a ring (1, and the ends (1 d are secured in the ring (1 by spreading the ends (I (I, as shown in Fig. 9. The ring d may be made of wire wound in the desired form and then dipped in solder or may be made of stiff flat metal.

Jointed to the collarD at d (Fare the coverfasteners E E, which are bow shaped, as shown, and made of flat spring metal. The free end of the. fastener E is bent inwardly at about right angles to the main portion of the fastener to form the catch e, and then is bent obliquely upwardly and outwardly to form the lip e. The top of the cover F is formed with agroove f, against the outer wall of which the catch 6 is caused to press by the tension of the spring-fastener E. The bottom of the groove fis inclined inwardly and upwardly and th'e'angle of inclination may be less than that at which the lip e is bent,

in which case there is a space between the cover and the lip for the insertion of a pry, or the lip 6 may be allowed to rest upon the bottom of the groove f and to project slightly over the inner edge f of thev groove. This construction will also allow of the ready insertion of a pry under the lip c. As will be readily understood, the fastener E is released by inserting a suitable pry under the lip e and prying the catch e out of engagement with the groove f. Under the flange f of the cover F in my preferred form of construction is a groove f in which is inserted a rubber ring G. The rubber ring G is preferably hollow or of tubular cross-section; but I do not wish to be understood as limiting myself to this form of construction. By thus securing the sealing-ring to the cover all danger of losing or mislaying the ring is avoided and the'ring is always in place, the ring and the cover forming practically one. Furthermore,

all danger of splashing the hot, fruit over the ring is avoided, with its attendant annoyance and disadvantage. By making the ring hollow greater resiliency is obtained and a limited amount of movement of the cover F is permitted without affecting the air-tightness of the joint between the cover F and the jar A and a limited amount of play between thespring-fastener E and the cover F when applying the fastener is allowed for. Another advantage lies in the ease with which the cover F may be removed after the release of the spring-fastener E.

The fasteners E E may be used detached from the collar D, which in that case is dispensed with. The only change made in the fastener E in passing to the form E is in the lower end, which is not turned upon itself to engage the collar D. The lower curved end of the fastener E engages under the flange B and the upper end engages in the groovef in the cover F, as before explained. The tension of the spring-fasteners E and E maybe made as great as desired by the selection of the proper quality of spring metal.

Vhat I claim is 1. Asanew article ofmanufacture,a springclasp fastener for vessel-closures, said fastener comprising a spring-clasp, the upper portion of which is formed with a catch adapted to engage in a groove in the vessel-cover and provided with a lip for the engagement of a releasing-pry.

2. In aclosure for air-tight vessels, the combination of a vessel provided with a projecting flange near its mouth; a cover for said vessel formed witha groove on its uppcrsurface in which engages the catch of the coverfastener; a sealing-ring which seals the joint between said vessel and its cover; and a spring-clasp fastener, the upper portion of which is formed with a catch which engages in a groove in the said cover, and provided with a lip for the engagement of a releasing-pry.

3. In aclosure for air-tight vessels, the combination of a vessel; a cover for said vessel formed on its upper surface with a groove in which engages the catch of the cover-fastener; a sealing-ring which seals the joint between the said vessel and its cover; a collar secured about the neck of said vessel; and a springclasp fastener secured, at its lower end, free to rotate on said collar, the upper portion of said fastener being formed with a catch which engages with a groove in the said cover, and provided with a lip for the engagement of a releasing-pry.

4:. In a closure forair-tight vessels, the combination of a vessel; a cover for said vessel formed on its upper surface with a groove in which engages the catch of the cover-fastener; a pneumatic sealing-ring which is secured to said cover, and which seals the joint between said vessel and its cover; a collar secured to the neck of said vessel; and a spring-clasp fastener secured atits lower end, free to rotate on said collar, the upper portion of said fastener being formed with a catch which engages in a groove in the said cover, and provided with a lip for the engagement of a releasing-pry.

5. In a closure for vessels, the combination of a vessel; a cover for said vessel, formed on its upper surface with a groove in which engages the catch of the cover-fastener; a collar secured to the neck of said vessel; and a spring-clasp fastener secured free to rotate on said collar, the upper portion of said fastener being formed with a catch which engages in a groove in the said cover, and provided with a lip for the engagement of a releasing, PW-

In testimony whereof I affix my signature in presence of two witnesses.
